CHARLES C. KOPLIN, OF BARTLESVILLE, OKLAHOMA.

SUSPENDED PUMPING POWER.

Specification of Letters Iatent.

Patented Mar. 8, 1921.

Application filed. July 6, 1920. Serial No. 394,273.

1' 0 all whom it may concern Be it known that 1, CHARLES C. Kornm, acitizen 01 the United States, residing in the city of Bartlesville andState of Oklahoma, have invented new and useful Improvements inSuspended Pumping Powers, of which the following is a specification,reference being had to the accompanying drawings.

The present invention pertains to pumping powers for use in oil fieldsfor the purpose of pumping oil from the wells, or for like purposes. Thepumping unit as now employed comprises a master wheel with its axle andupon the axle is rigidly mounted a circular cam provided with a slidingyoke upon its Outer periphery, to which yoke may be attached any numberof pull rods. The ends of these pull rods are then extended and attachedto the pumps in the field. In this way a large number of scattered pumpsmay be operated from one pumping unit.

The primary purpose of the present invention is to provide an improvedform of construction for such pumping unit which may be called asuspended pumping power, wherein two eccentrically mounted yokes aremounted upon one master wheel and are pierced with holes around theirouter peripheries as means for attaching the pull rods'.

A further object is to provide a mechanism of the class described havingfacilities for operating a greater number of pumps than can be operatedwith the ordinary pumping unit.

A further object is to provide a mechanism of this character constructedin a simple, practical and efficient form best adapted to carry out thepurposes intended.

In the drawings as embodying the preferred form of construction of thisinvention Figure 1 is a frontal elevation showing my improvement as setup and in operation.

Fig. 2 is a top plan view.

Fig. 3 is a side elevation.

Referring more particularly to the drawings, my invention consists ofthe large annular track ring 1, around the inner periphery of which arejournaled a plurality of flanged rollers 2. Within the flanges of theserollers is rotatively mounted the master wheel 3. Around and upon theunder side of this wheel 3 is rigidly mounted the beveled circular rack4, adapted to mesh with the pinion 5. The pinion 5 is rigidly mounted atthe inner end of the shaft 6, which shaft is journaled in the frame at 7and is provided at the outer end with the rigidly mounted power wheel 8.The apparatus as so far described is horizontally mounted upon the frame9. Upon the upper face of the master wheel 3 is rigidly mounted theprimary crank head 10, eccentrically of the axis of the master wheel 3.This crank head 10 is provided with a groove 11 within which isrotatively mounted the annular yoke 12. Upon the crown of the crank head10 and so as to clear the yoke 12 is rigidly mounted the horizontalcrank arm 13, same being extended directly across the central axis ofthe master Wheel 3, and upon the outer end of this crank arm is rigidlymounted another or secondary crank head 14:, same being likewiseeccentrically located relative to the axis of said master wheel. Uponthis secondary crank head it is rotatively mounted the secondary yoke15. Both the primary yoke 12 and the secondary yoke 15 are pierced witha plurality of pull rod holes as shown at 16 and 17, same being adaptedto receive the inner ends of the pull rods 18 and 19, the outer endsthereof being extended to the pumps for the purpose of operating thesame.

It is obvious that as the power wheel 8 rotates the pinion 5, the masterwheel 3 is caused to revolve within the rollers 2, thus causing theyokes 12 and 15 to move eccentrically around the axis of the masterwheel 3, and causing the pull rods 18 and 19 to oscillate backwardly andforwardly, for the purpose of operating the pumps.

While I have herein described a certain specific method of constructingand assembling the elements or" my invention, it is understood same maybe varied in minor details, not departing from the spirit of myinvention as defined in the appended claim.

\Vhat I claim to be new and patentable is:

A mechanism. of the character described, comprising a supporting frame;a shaft horizontally journaled in the frame; a power wheel rigidlymounted at the outer end of the shaft; a inion rigidly mounted at theinner end of the shaft; a track ring rigidly and horizontally mounted onthe frame above the pinion; a plurality of flanged rollers mountedaround the inner periphery of the track ring; a master Wheel rotativelymounted within the track ring and supported by sald rollers as bearings;a cireular rack rigidly mounted around the centrically of the axis ofthe master Wheel; underside of the track ring, in mesh with yokesrotatively mounted upon said primary said pinion; a primary crank headrigidly and secondary crank heads; and pull. rod mounted upon the upperside ofthe master holes pierced through the said yokes, as

crank arm rigidly and horizontally mounted to the pumps.
